24033	[Patch] There should be a validator warning for the deprecated key building:roof	goodidea	team	"The key `building:roof=*` is deprecated (according to the wiki in favor of `roof:material=*`, see https://wiki.openstreetmap.org/wiki/Key:building:roof). There should be a validator warning for this deprecated key. 

A note: a saw this key not only with material values, but also with roof shape values, e.g. `building:roof=flat` (or gabled/hipped/...). According to taginfo, espacially the tag `building:roof=flat` is still used 10627 times! See https://taginfo.openstreetmap.org/keys/building:roof#values. So maybe the warning text of the validator should not only specify `roof:material=*` as a replacement (like in the wiki), but also `roof:shape=*` ...

One more note: At the moment there is already a validator warning for another similar deprecated key `building:roof:shape=*`, see https://josm.openstreetmap.de/changeset/17942/josm.
